Warranty Coverage

Mercury Warranty Information

World-class marine products backed by world-class warranties. We stand behind everything we build. And we go the extra mile to make sure your Mercury® experience is the best it can be. On the water and off.

Every Mercury MerCruiser® and Mercury Diesel inboard and sterndrive conforms to California's emissions regulations. Qualifying engines manufactured during or after 2003 are backed by a three year (or 480 hour) warranty for any defective part that violates the standards of the California Air Resources Board - including the cost to diagnose the failure.

Mercury MerCruiser® sterndrives, inboards, and tow sport inboards have a standard limited, non-declining warranty. The length of this warranty depends on the model but can last up to three years. Certain boat brands, whose manufacturers have met the requirements for the Mercury Installation Quality Certification Program, carry an additional year of warranty on the MerCruiser engine.
